A skydiver jumps out of an airplane and begins to freefall. Once he reaches maximum velocity, which statement below would best describe the forces acting on the skydiver? MS-PS2-2
a)
Forces are unbalanced. Gravity pulls the skydiver, causing him to accelerate ever faster towards the ground.
b)
Forces are balanced. Since the skydiver is in freefall, he is experiencing no gravity at all, so no forces are acting on him.
c)
Forces are balanced. The pull of gravity is being countered by the friction of the air, so the skydiver, though falling, FEELS weightless.
d)
Forces are unbalanced. The skydiver is hitting the inertia of the air, which he can't push through so his fall slows.
2.
The image below shows one of the phases of the moon. Which phase is it, and what kind of tide would we expect to see with this phase? MS-ESS1-1 MS-PS2-4
a)
Waxing Crescent, spring tide
b)
Waning Gibbous, neap tide
c)
First Quarter, neap tide
d)
New Moon, spring tide
3.
Why is magma mostly liquid? MS-ESS2-2 MS-ESS2-1 MS-PS3-4
a)
Mountains keep the magma liquefied.
b)
Nothing. Magma is mostly solid.
c)
Magma has special chemicals mixed in to keep it liquid.
d)
Earth's core is under enormous pressure so it remains very hot. That heat conducts out to the mantle, keeping the rock melted.
4.
Compare the statements below, and select which is correct: MS-ESS2-1
